Paul Sabatier (1854-1941) winner of the Nobel Prize in Chemistry in 1912 and discoverer of the reaction in 1897. The Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 3 MPa [1]) in the presence of a nickel catalyst.
In methanogenesis, carbon monoxide, carbon dioxide, and methanol are converted to methane, provided suitable reducing agents. [3] Methanogenesis by methanogenic archaea is reversible. [4] In photosynthesis, carbon dioxide and water is converted to sugars (and O 2), the energy for this (thermally) uphill reaction being provided by sunlight.
Syngas is produced from biomass gasification and further converted into green methanol. [62] Another method of producing green methanol involves combining hydrogen, carbon dioxide, and a catalyst under high heat and pressure. [61] To be classified as green methanol, the hydrogen must be green hydrogen, which is produced using renewable ...
Methanol can be produced from a variety of sources including fossil fuels (natural gas, coal, oil shale, tar sands, etc.) as well as agricultural products and municipal waste, wood and varied biomass. It can also be made from chemical recycling of carbon dioxide. Nobel prize laureate George A. Olah advocated a methanol economy. [1] [2] [3] [4]
The electrochemical reduction of carbon dioxide, also known as CO2RR, is the conversion of carbon dioxide (CO 2) to more reduced chemical species using electrical energy. It represents one potential step in the broad scheme of carbon capture and utilization .
Methanol can be converted to olefins using zeolite and SAPO-based heterogeneous catalysts. Depending on the catalyst pore size, this process can afford either C2 or C3 products, which are important monomers. [6] [7] Methanol to olefins technology is widely used in China in order to produce plastics from coal gasification.
Methanation is the conversion of carbon monoxide and carbon dioxide (CO x) to methane (CH 4) through hydrogenation. The methanation reactions of CO x were first discovered by Sabatier and Senderens in 1902. [1] CO x methanation has many practical applications.
A 1965 report suggested synthesizing methanol from carbon dioxide in air using nuclear power for a mobile fuel depot. [62] Shipboard production of synthetic fuel using nuclear power was studied in 1977 and 1995. [63] [64] [65] A 1984 report studied the recovery of carbon dioxide from fossil fuel plants. [66]
